To alt whom it. may concern.:

Beitknownthatfwe, JOHN J. MoINTYRE,and

HERBERT BAGSHAW, citizens of the. United States, residing at Hartford, in the county ot' Hartfordand State oi' Connecticut, have invented certain new and useful Improvements in Hose-Binders, 'of 'whichthe following is a specification. Y

This invention relates to and has for an object \to provide an improved hose-binder.

.In the drawings accompanying and forming a part of this specication, Figure 1 represents an embodiment of the present improvement, the same being a side view partly broken away andl in longitudinal section, the parts being shown applied to a hose and inthe initial bindingposition. Fig. 2 is a similar view showing the parts tion. Figs. 3, 4, and 5 are longitudinal sections of the coupling-block, the expander, and the binder, respectively, disassembled.

The binder herein illustrated comprises a coupling member or block 7, adapted to be fastened to some'suitable connection, as occasion may demand, and which has a flange 8 at one end, back of'which flange there is a channel 9. The flange in the present instance is shown as of greater 'inside diameter than the inside diameter of the body portion 10 of the coupling member. This flange and groove are adapted for the reception and securement of an expander 11, which hasa groove 12 to receive the flange 8 and a iiange 13 to enter the groove 9, which ilange 13 is illustrated as having a chamfered edge 11 to enable the assemblage of the expander with the coupling member by being forced together, and if the parts are bent ont of'shape'they may be re-formed in some suitable manner. The expander is shown as having a wedge or vconoidal expanding portion 15, adapted to enter the hose and expand the same. The coupling member is also shown provided with external screw-threads 16,

adapted .to mate with the internal screwthreadsl' of the binding member 18, which binding member is shown as having an enlarged chamber portion 19, and-beyond the chamber portion it is provided with a binding- Bange 20, which is shownl as parallel with the axis of rotation of such binding member and also of the expander. Consequently it will be parallel with the outer face of the hose to which it is to be applied. This flange may in practice be provided with a number of abutin their completely-bound posi.

ments or teeth, (illustrated herein as 21, 22, and 23.) The binder may be provided with some means of engagement to properly hold it when screwing or unscrewing it, and in the present illustration lugs 424 are'shown adapted to be engaged by a Spanner in a manner well known to those familiar with this class of device.

In Figs. 1 and 2 the parts are shown as assembled and a portion of hose in the control of the parts. By reference to Fig. 1 it has engaged the first thread upon the coupling (position and will be drawn over the expander upon continued rotation of the binder-or of the coupling member. The expander has a loose or swiveling it with the coupler sufiicient to give it a self-centering action and also to permit the expander to move with the hose independently of the coupling member. It will be observed that the connection between vthe coupler and expander, or rather the bearing-faces, are square shoulders, the coupling' member having shoulders or faces 31, 32, and 33 to abut shoulders or faces 34, 35, and'36, respectively, upon the expander. After the hose has been securely bound into position it will be observed (see Fig. 2) that the end or edge 27 of the expander extends outwardly beyond the end 28 of the binder and that the inner face 29 of the binder is substantially of the same circumference as the inside face 30 of the hose, `and this structure will prevent an frequently occurs with the binde-r, and particularly those wherein the edge of the binder or expander end on the same place or the expa'nderends inwardly of the end of the binder.

By making the binding-face of the binder substantially cylindrical or cylindrical with engaging abutments the hose will be bound in position with a less amount lof tension in the binding operation, and the liability to rupture a rubber hose will be lessened, and when the hose is under pressure and receives a shock, as by cutting oi the flow at the nozzlethe shock will be absorbed to some extent and eased at the point where the hose i's most securely bound-that is, we might assume that the tooth 23 compresses and binds about one-third as much as the ring ortooth 21 and that the ring or tooth 22 binds and 2 holds about two-thi-rds as much as the ring l or tooth 21. This organization will bring will be seen that the screw-thread on the binder member and that the end 26 of the hose is in inwardly-projectingarchingof the hose, which 2 'masse the shock gradually to the point Where the hose is most strongly clamped.

The coupling when in service engages the hose at a zone near its end, said zone being disposed longitudinally and circumferentially of the hose and slightly removed from the end, and the clamping action throughout said zone increases in force 'of engagement toward the end of the hose, or, reversely stated, the strongest force of engagement is at the end ofsaid clamped zone nearest the hose end and gradually decreases to zero at the end toward the main portion of the hose.

By the provision of the chamber 19 the binding action of lthe parts will come upon the hose ata region remote from its end. This is especially desirable in a fabric hose, since it is well known that fabric is not as strong at its cut edge as it is inwardly of such edge. The present binder not only clamps the hose at a region of strength, but also shields the free end, and this Without increasing the bulk of the binder.

Having thus described our invention, we claim- The combination with a coupling member havingachannel 1n its inner face near its end forming a ange, the face of the walls of which fiange constitutes square shoulders, of y ed connection with the coupling member and 1 having a portion chambered for the accommodation of the end of the hose and carrying a binder beyond said chamber provided with a series of hose-engaging faces arranged on a cylindrical plane and when in clamping position overlying the inner portion of the expander and a portion of said expander projecting beyond the said binder.
